Errata
Decision-grade STM32 hardware evidence for engineers and agents.
Errata is a hosted MCP and REST service for retrieving verified hardware facts with the conditions and sources needed to use them safely. It resolves exact STM32 targets, joins registers, pins, electrical limits, and silicon errata, and states when evidence is missing instead of inventing a nearby answer.

What the service guarantees
- Every served engineering fact has claim-level provenance and structured conditions.
- Broad part identifiers remain ambiguous until the caller selects hardware.
- Hardware filters run before lexical ranking.
not_indexedandno_matchare explicit outcomes, not invitations to guess.- Corpus releases are immutable and can be pinned in requests.
- Production publication advances only after source, integrity, benchmark, and attestation gates pass.

The important boundary
Catalog coverage and verified-fact coverage are different. Errata can identify a part and its official documents without claiming every possible parameter has been published or fused. Always inspect status, coverage, gaps, conditions, and provenance before making a design decision.
